Red Hat Bugzilla – Bug 233296
fence_scsi needs to work with multipath configurations
Last modified: 2009-04-16 16:28:01 EDT
Description of problem:
Current scsi reservations does searchs of devices attached to each of the
cluster nodes. There are potentially issues when multipath is configured to
ensure that all of the paths get properly registered and used when running the
fencing operations. This bugzilla is to ensure we track down and either
validate that fence_scsi and multipath work, or fix the problems that occur.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
There are several reasons that fence_scsi will not work with multipath
configurations. One limitation is that it would only work with active/active
controllers. Another reason is that dm-multipath will not pass the SCSI ioctl's
to all devices that comprise a multipath device.
